The relationship between agriculture and blockchain

1. The application of blockchain in the field of agriculture is developing day by day. Jiminsheng connects the front, back, left and right blocks of "things" into a chain with one technology, but the original data of each block can not be tampered with. It is a technology of "each mole chain" in the field of Internet of things that can be trusted by participants.

2.

A: first, the connotation of blockchain

blockchain is a distributed shared ledger and database, which is decentralized, tamper proof, traceable, collective maintenance, open and transparent

Agricultural traceability is the most complex and difficult part of food traceability. At present, there is no complete agricultural proct traceability system based on food safety proction and whole process supply chain management

2. The most important part of the construction of agricultural traceability system is "one center and three moles", which is a traceability cloud data center and three moles of procers, regulators and consumers

Third, composition of blockchain

blockchain system is composed of data layer, network layer, consensus layer, incentive layer, contract layer and application layer

3. The decentralization of blockchain will greatly rece the cost of Internet maintenance and enhance the intelligent and large-scale level of Agricultural Internet of things. At the same time, the agricultural procts traceability system based on blockchain technology solves the trust crisis of consumers for procts, and makes people's dining tables healthier and safer
in the field of agriculture, what are the trends of blockchain agriculture
1. Internet of things + UAV + blockchain
logistics ensures the interconnection of everything, UAV provides proction management services, and blockchain provides recording and traceability technologies. It will be concive to the development of precision agriculture, rece pesticide investment and improve the quality of agricultural procts
2. Blockchain + data + artificial intelligence
the application of blockchain in agriculture can eliminate information asymmetry to the greatest extent, improve the information transparency and timely response ability of the whole instrial chain, and realize the value-added of the whole instry
the integrated development of blockchain + data + artificial intelligence can maximize the value of agricultural big data and rece the input cost< In early February, the Chinese government issued "guidance on the revitalization of rural financial services". The new framework proposed this time is part of the financial service efficiency improvement plan in the National Rural Revitalization Plan
blockchain + agricultural finance will provide a convenient way for small farmers' loans and bring authenticity and predictability to the credit investigation of agricultural financial institutions
4. Blockchain + rural logistics
e to the small distribution of rural logistics, package loss and difficulty of agricultural procts ascending are caused. But blockchain technology can solve these problems
5. Blockchain + agricultural supply chain
this kind of application is the reason why major shopping malls graft blockchain. For example, Wal Mart, Carrefour and other large supermarkets bring the whole fresh food and food supply chain into the block chain management, so as to rece costs and improve proct safety. At present, Cargill, an American agricultural giant, is vigorously developing the application of blockchain + agricultural supply chain finance
in addition to agriculture, the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

4. At present, the combination of blockchain and agriculture can be divided into two parts:
one is the traceability mode, which is commonly used nowadays. All agricultural activities, from planting to proction and sales, are recorded on the blockchain, so as to achieve the purpose of proct traceability. However, this method costs a lot, and usually has a special team or company to do it, Because the follow-up after-sales is very troublesome
the second is to use the form of blockchain token combined with the online mall to sell agricultural procts through the Internet. Instead of the usual cash, it uses the form of digital currency to circulate, which is equivalent to linking with the blockchain

5. The value of blockchain lies in safety, and the value of blockchain agriculture is for food safety, and these data have a very important reference role for the reproction of agricultural procts
with the development of value oriented agriculture, precision agriculture and central agricultural system, this kind of blockchain technology will promote the continuous development of the agricultural instry, and its technology can also bring more jobs
blockchain agriculture has existed for a long time, but some places are not mature enough, especially traceability. However, a dmtc agricultural traceability project was launched this year to fill the gap
in terms of data collection, through the application of artificial intelligence and Internet of things technology, it runs through the whole agricultural ecological chain. During agricultural proction, it automatically records the proction environment data and proction process data of agricultural procts, when agricultural procts are transported, it automatically records the transportation data, and when selling, dmtc terminal connects with intelligent micro supermarket to collect consumer behavior data, Through the popularization of intelligent micro supermarket, terminals are all over the living quarters, collecting rich data for instrial development, and carrying the value transmission and information transmission of agricultural ecological chain more perfectly

6. For example, the vonetracer traceability system of wangchain technology can record the information of planting links from the purchase of seeds / fertilizers, sowing, irrigation, fertilization and other systems to the information records of picking and testing, and collect and monitor the whole process data according to different batch numbers, so as to realize the traceability management of planting link information.

7. What problems does blockchain solve in agriculture
1. Traceability of agricultural procts
traceability of agricultural procts has always been a pain point in agriculture. The blockchain technology can not tamper with the records, so from the proction end to the circulation end of agricultural procts, consumers have detailed data, which can realize consumers' clear consumption and improve consumers' willingness to buy
traceability of agricultural procts can improve the safety of agricultural procts and food
2. Information transparency
in addition to traceability, the information of procers and demanders is also opaque
once blockchain technology is applied to agriculture. Through big data analysis, we can establish credit rating reference for growers and purchasers; Smart contracts are used to ensure fair trade between growers and purchasers. At the same time, blockchain technology can improve the contractual spirit of the buyers and sellers of agricultural procts
in addition, with the emergence of the block chain in the food supply chain, this can simplify the process, because the data management system, which brings a series of brokers, farmers, processors, distributors, regulators, retailers and consumers into its radar range, has become more transparent
3. Cost rection
after the application of blockchain technology, the cost of proction and circulation will be greatly reced. For example, blockchain technology solves the function of automatic information storage and database, which reces the input of labor and other facilities
in addition, the blockchain and applications realize the interconnection of everything, helping manufacturers and channel providers to rece various expenses. At the same time, the rection of proction and circulation costs will also rece the price of agricultural procts, and ultimately consumers will benefit
of course, in addition to the above three reasons, there are agricultural subsidies, land registration and other aspects. Blockchain technology can also be applied to solve the problems of corruption and rights and interests
therefore, the application of blockchain technology in the field of agriculture is recognized by people at all levels
the core advantage of blockchain technology is decentralization, which can realize point-to-point transaction, coordination and cooperation based on decentralized credit in a distributed system without mutual trust by means of data encryption, time stamp, distributed consensus and economic incentive, so as to solve the high cost and low cost of centralized institutions Low efficiency and data storage insecurity provide solutions
the application fields of blockchain include digital currency, token, finance, anti-counterfeiting traceability, privacy protection, supply chain, entertainment, etc. with the popularity of blockchain and bitcoin, many related top domain names have been registered, which has a great impact on the domain name instry.

8. Now blockchain + big data + agriculture is very popular. You can learn about the ecological agreement, which takes tea enterprises as the core.

9. After the combination of blockchain and agricultural insurance, agricultural insurance will have a lot of room for improvement in agricultural intellectual property protection and agricultural property transaction, which will greatly simplify the agricultural insurance process. If intelligent contracts can also be used, once agricultural disasters are detected, the compensation process will be automatically started, with higher compensation efficiency
